MBootstrap Angular Material Animation 不适用于输入字段

我正在尝试使用“带有背景动画边框的输入 - Material 2.0”输入，如下所示：https : //mdbootstrap.com/docs/jquery/forms/inputs/#animated-inputs

我也在使用“延迟加载”方法（关于路由）。

这是原版

这是它应该如何工作

这就是它~实际上~所做的

问题是“输入字段”无法正常工作。输入数据时，字符“覆盖”标签

How can this be fixed? If this requires a specific module, where can one find information on the necessary modules needed with each component? Or - does one have to import ~all~ MDB Modules (or Material modules) when creating "separate components" (usingng generate component) in the module.ts file for the "separate component"?

ETA:

I have seen this message here: Angular Material Date-Picker is not working properly

1. I have added Angular Material to the project (see package.json below)

2. I have tried to add BrowserAnimationsModule as follows in authorizatin.module.ts as follows:

   import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; import { AuthorizationRoutingModule } from './authorization-routing. module';

   import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

   [... snip ...]

   @NgModule({ declarations: [ authRoutingComponents ], exports: [ authRoutingComponents, AuthorizationRoutingModule ], imports: [ BrowserAnimationsModule, CommonModule, ButtonsModule, AuthorizationRoutingModule,

but got the following error

Uncaught (in promise): Error: BrowserModule has already been loaded.

Again, any info on the issue is appreciated.

Error I am getting when adding BrowserAnimationsModule
